It is what it is, the scheme allows fair wear and tear and realise for a lot of disabled folk a car is a vital tool and so some get used harder then others.
I agree because as these cars are for disabled persons there is bound to be slight damage to the car that would not happen had it been a none disabled persons car.
For example my previous car, Golf TSi had damage to the driver seat lumbar support and to the drivers door seal where for myself to get into the driving seat had to lean heavily on the centre pillar causing the seal damage, then privet into the seat causing extra wear on the lumber support of the seat.
With my current being more suitable and higher off the ground that type of damage is not showing but as I now carry my assembled scooter in the back of the car the wheels of the scooter is causing extra ware on the back of the back seats.
None of these things would cost more than a couple of hundred at most to fix but it is extra wear and damage cause by my disability.
